Climate change projection of snowfall in the Colorado River Basin using dynamical downscaling
[1] Recent observations show a decrease in the fraction of precipitation falling as snowfall in the western United States. In this work we evaluate a historical and future climate simulation over the Colorado River Basin using a 35 km continuous 111 year simulation (1969–2079) of the Weather Research and Forecasting (WRF) regional climate model with boundary forcing from the Hadley Centre for C...
متن کاملFuture climate change impact on hydrological regime of river basin using SWAT model
Hydrological components in a river basin can get adversely affected by climate change in coming future. Manipur River basin lies in the extreme northeast region of India nestled in the lesser Himalayan ranges and it is under severe pressure from anthropogenic and natural factors. Basin is un-gauged as it lies in remote location and suffering from large data scarcity. This paper explores the imp...
متن کاملClimate change scenarios generated by using GCM outputs and statistical downscaling in an arid region
Two statistical downscaling models, the non-homogeneous hidden Markov model (NHMM) and the Statistical Down–Scaling Model (SDSM) were used to generate future scenarios of both mean and extremes in the Tarim River basin,which were based on nine combined scenarios including three general circulation models (GCMs) (CSIRO30, ECHAM5,and GFDL21) predictor sets and three special report on emission sce...
متن کاملAnalysis of Streamflow Changes under Climate Change Using Rainfall-Runoff Model in the Kor River Basin
Abstract In this study, the predicted monthly temperature and rainfall data from HadCM3 model (base period, ۱۹۷۲-۲۰۰۱) and next period (۲۰۱۱-۲۰۴۰) under A2emission scenario were used to investigate the impacts of climate change on runoff variations in the Kor river basin. HadCM3 model output was downscaled based on a temporal downscaling approach (Change Factor) and spatial downscaling appro...
متن کاملclimate change assessment over iran during future decades, using statistical downscaling of echo-g model
in spite of considerable increase in the resolution of general circulation and regional models, none of these models are capable to predict and downscale the meteorological outputs in the scale of meteorological station.in this regard, different dynamical and statistical models have been developed for downscaling outputs of gcms. in this paper, grided meteorological outputs of general circulati...
